I did some tests with 
http://seeautz-projekt1.googlecode.com/svn/trunk/seeautz/Additional%20Libraries/OpenAL%201.1%20SDK/samples/media/fiveptone.wav

Results:
OpenAL 1.11.753 and surround51: everything ok
OpenAL 1.11.753 and dmix6: no LFE sound

OpenAL 1.12.854 and surround51: alsa.c:743: set buffer time near
failed: Invalid argument
OpenAL 1.11.753 and dmix6: no LFE sound
